DuPont Kalrez. Oil and Gas Product Selector Guide. Technical Information April 2017

Transcription

1 DuPont Kalrez Oil and Gas Product Selector Guide Technical Information April 2017 DuPont has more than 30 years of experience providing perfluoroelastomer seals to the oil and gas industry. Over this time, reservoir pressures and temperatures have both risen while an increased focus on safety margin has driven wider use of this most resilient of elastomeric material classes. DuPont scientists have developed seals that can offer Rapid Gas Decompression (RGD) resistance to ISO, Norsok and Total industry certifications while resisting the harshest well fluid environments at temperatures that include both arctic surface conditions and high downhole temperatures and pressures. seals deliver proven reliability in extended lifetime services both above and below ground.

Back up rings increase part count, make assembly more complex and add significant cost. changes this paradigm. By having exceptional mechanical strength, even at high temperatures and pressures such as +232 C (450 F) and 150MPa (22,500 psi) does not extrude. This not only allows the efficiencies described above, but also significantly improves low temperature sealing performance at high and low pressures. shapes O-rings and customer parts

6 Product Description DuPont is an exceptional general purpose compound for use in the oil and gas industry. DuPont perfluoroelastomer parts deliver durable, reliable sealing solutions for applications requiring excellent rapid gas decompression (RGD) properties combined with high hardness and high modulus. Some application areas include downhole equipment such as drilling and completion tools as well as industrial equipment including pumps and valves. has been certified by two independent labs to meet rigorous requirements for resistance to RGD. In addition to demonstrated, DuPont seals have other chemical and temperature properties that provide superior performance. Chemical resistance: can be resistant to sour multi-phase fluids containing H2S as shown by the external NORSOK M-710 Rev 2 Sour Fluid aging resistance certification provided by MERL (UK). Broad temperature capability: retains high levels of resilience up to temperatures as high as 250 C (482 F) and down to 21 C ( 5.8 F). Under pressurized sealing conditions, 0900 has demonstrated low temperature performance down to 40 C ( 40 F) in customer laboratory tests. Highest rating of 0000 in severe test conditions demonstrates outstanding of DuPont. (0000 meaning no damage) Tested according to Norsok M710 rev2 standard (K312 (15.24x5.33mm) O-ring; 67% groove fill; Test gas 10% CO2 in methane) Spectrum 6375 DuPont 6375 perfluoroelastomer parts are designed to give outstanding performance in the widest possible range of chemicals and over a broad range of temperatures. This product is an excellent choice for use in acids, bases, amines, steam, highly alkaline solutions and many other aggressive chemicals. The compound is designed for continuous upper service temperature of 275 C (527 F). This high temperature stability translates into increased chemical resistance and longer life over all temperature ranges, even if high temperature process excursions occur. Spectrum 7090 DuPont Kalrezâ Spectrum 7090 perfluoroelastomer parts are specifically targeted for use in applications requiring high hardness/higher modulus properties. These specialty black parts have excellent mechanical properties including compression set resistance, seal force retention, response to temperature cycling effects and rapid gas decompression resistance. Kalrezâ Spectrum 7090 perfluoroelastomer parts are well suited for both static and dynamic sealing applications, especially applications that require extrusion resistance at higher temperatures. They also offer outstanding thermal stability and chemical resistance. A maximum application temperature of 325 C (617 F) is suggested. Short excursions to higher temperatures may also be possible.

7 Spectrum 0040 DuPont Spectrum 0040 perfluoroelastomer parts are specifically designed for low temperature environments where significant chemical resistance is required. Its chemical resistance is close to Spectrum 6375 which is the reference in the chemical processing industry. In addition, the proprietary polymer and cure technology enables the low temperature sealing performance (-42 C) of 0040 parts typically unattainable from other perfluoroelastomers parts. Spectrum 0040 is an excellent choice in applications for the oil and gas industry, or for other applications, where chemical resistance and elasticity are required in some of the coldest environments. Spectrum 0040 can also operate at temperatures up to 220 C DuPont 3065 is a long- standing compound that has proved its performance over more than 30 years in the field. It is a highly-filled product containing carbon black and fiber reinforcement, designed to function without extrusion under extreme pressure. It has good all round chemical resistance and excellent resistance to sour oil and amines has an upper service temperature of 288 C (550 F). The mechanical properties and chemical resistance of 3065 make it the best choice for many oil and gas well applications. In these applications, it is normally used in the form of V-rings and other custom parts rather than O-rings. With correct design 3065 can remove the need for back-up rings.
